The tr adverb, modeled after Amend is an adaptation of RogerHui's simultaneous shape preserving translator. I was looking for the pattern for a while.

Here is more solutions

H2a, externalized connector

```extH2a=: 0&\$: : (4 : 0)
if. y.=0 do. ,:,:'o' return. end.
h=. |:'|-' '-|'tr 1 extH2a y.-1
h,.(x. con #h),.|."1 h
)

con=: 4 : 0
c=. <.-: y.
p=. '-'(],,)c#' '
o=. (c#' '),'o',c#x.{' |'
p,.o,.p
)```

H3, halved iterations, eliminating transposition

```cc=: (],1:,])@<.@-:
c2=: cc #"1 (' | ', ' o-',:' | ')"_
c3=: cc #   (' - ',.' o ',.' - ')"_
c4=: cc #   (' - ',.' o|',.' - ')"_
c34=: c3`c4@.

extH3=: 0&\$: : (4 : 0)
if. y.=0 do. ,:,:  'o' return. end.
if. y.=1 do. ,:'o-o-o' return. end.
g=. h ,  (   c2  {:\$h) ,  |.   h=. 1 extH3 y.-2
g ,. (x. c34   #g) ,. |."1 g
)```

H4, semi-tacit by reusing arguments

```extH4=: 0&\$: : (4 : 0)
if. y.=0 do. ,:,:  'o' return. end.
if. y.=1 do. ,:'o-o-o' return. end.
(,.(x.c34@#,.|."1))(,(c2@{:@\$,|.)) 1 extH4 y.-2
)```

H5, more tacit by removing controls

```h0=: (,:,:'o')"_
h1=: (,:'o-o-o')"_
extH5a=: 4 : '(,.(x.c34@#,.|."1))(,(c2@{:@\$,|.)) 1 extH5 y.-2'
extH5=: 0&\$: : (h0`h1`extH5a@.(2&<.@]))```

``` 'd2 d3 d4'=: (3 3 3\$' |  o- |    -o-      -o- | ')
'`e2 e3 e4'=: (#"1&d2)`(#&d3)`(#&d4)@cc
extH6 =: h0`h1`extH6a@.(2&<.@])
extH6b=: h0`h1`extH6c@.(2&<.@])
extH6a=: [: (,.(e3@#,.|."1)) [: (,(e2@{:@\$,|.)) [: extH6b -&2
extH6c=: [: (,.(e4@#,.|."1)) [: (,(e2@{:@\$,|.)) [: extH6b -&2```

H7, non-recursive tacit

```'`f0 f1 f2'=: (, (c2@{:@\$, |.))`(,. (c4@#,. |."1))`(,. (c3@#,. |."1))
extH7=: f2@:f0@:( f1@:f0@]^:((-&2 <.@% 2:)@[) )^:(1&<@[) h0`h1@.(2&|)```

ts vs. the original.

```   ts=: 6!:2 , 7!:2@]

't2 s2'=. |: (5: ts 'extH2 '&,@":)"0] 2*i.10
NB. ...
